What is it about this little black box that makes me want it so badly?

In a nutshell, a Drobo is a super easy proprietary redundant RAID-like hard drive enclosure that allows you to almost infinitely upgrade the drives inside. What is especially awesome other than its good looks is you don’t need to buy weird drive trays that aren’t available at a local Fry’s. All you do is just slide the bare drives into one of its four slots. There are little lights on the front that tell you when you’re running out of room or when a drive goes bad. You can mix and match drive makes and sizes. When the Drobo does runs out of room, just buy the big SATA drive you found on sale and replace the smallest drive. It then automatically prepares the drive. No down time, no fuss.
